Malicious code in opencode-skills-collection (npm)

Package bundles a collection of skill directories containing various helper scripts. Static pattern matches fired on routine network primitives: a Python scraper (bundled-skills/junta-leiloeiros/scripts/base_scraper.py) and an API server script (serve_api.py) that reference ping/GET/POST, a benchmark harness (bundled-skills/loki-mode/benchmarks/run-benchmarks.sh), an rclone install helper (bundled-skills/rclone-cli/scripts/install.sh) that runs curl https://rclone.org to fetch the rclone installer from its official project domain, and a youtube-notetaker verification script using curl against GET endpoints. Matches reflect keyword co-occurrence (curl/ping/GET/POST) in utility scripts rather than exfiltration shapes: no hardcoded attacker C2, no reads of installer-side secret paths (~/.aws, ~/.ssh, ~/.npmrc), no environment scraping, no obfuscated destinations, and no install-time lifecycle hook that auto-executes these scripts. The rclone install.sh fetches from rclone's official domain, which is aggressive-but-legitimate runtime tool installation rather than a dropper. The scripts fire only when a user explicitly invokes the corresponding skill, not on npm install.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
